Wondering how to cut your travel time? The \u5f84\u809a\u8de8\u7ebf\u6865 is quite a sight. It is an impressive feat of engineering. This bridge-tunnel system connects Shenzhen and Zhongshan.
Imagine driving across the \u5f84\u809a\u8de8\u7ebf\u6865. The journey now takes only 30 minutes. Before this link, the same trip would have taken two hours.
The \u5f84\u809a\u8de8\u7ebf\u6865 is not just one long bridge. It features an underwater tunnel. This tunnel runs between two artificial islands. Bridges connect each island to the mainland.
This mega-project officially opened in June 2024. It has quickly become a vital part of the Guangdong-Hong Kong-Macao Greater Bay Area.
But what makes the \u5f84\u809a\u8de8\u7ebf\u6865 so special? It holds ten world records. These aren’t just ordinary records. They are hilariously specific.
Consider these facts about the \u5f84\u809a\u8de8\u7ebf\u6865. It has the largest span for a fully offshore steel box girder suspension bridge at 1666 meters. The bridge deck reaches a height of 91 meters. That’s record-breaking. It also boasts the highest navigation clearance for a sea bridge.
The \u5f84\u809a\u8de8\u7ebf\u6865 has the largest offshore suspension bridge anchor. It uses 344000 cubic meters of concrete. It also features the highest wind resistance test speed for a suspension bridge. The bridge can withstand 83.7 meters per second. The largest steel bridge deck uses hot-mix epoxy asphalt paving. This covers 378800 square meters.
Dive into the tunnel portion of the \u5f84\u809a\u8de8\u7ebf\u6865. It includes the longest two-way eight-lane immersed tube tunnel. The tunnel stretches 5035 meters. It is the widest underwater steel shell-concrete immersed tube tunnel at 55.6 meters.
Each tunnel section used the largest single-volume cast for a steel-shell immersed tube. This uses self-compacting concrete. Each tube section contains 29000 cubic meters. The final joint of the immersed tube tunnel uses the widest repeatedly foldable M-shaped water stop measuring 3 meters.
Safety is key in the \u5f84\u809a\u8de8\u7ebf\u6865. It also includes the world’s first underwater expressway interchange and airport interchange. The tunnel has advanced firefighting and smoke exhaust systems. A team of 14 robots patrols the tunnel. They monitor pipes and cables. They can even direct traffic via loudspeakers.
Lights along the walls change color. Green indicates normal conditions. Red signals emergencies. Yellow to green lights guide evacuations.
The \u5f84\u809a\u8de8\u7ebf\u6865 complements the Hong Kong-Zhuhai-Macau Bridge. Together, these crossings ease travel in this densely populated region.
The \u5f84\u809a\u8de8\u7ebf\u6865 is more than a bridge. It’s a testament to modern engineering. It showcases Guangdong’s expertise. It provides innovative solutions for global transportation. Next time you cross, remember the ten world records beneath your tires.
